Sage green and white striped button up blouse, Sz M

Very flowy sage and white striped button up blouse. I found one tiny blemish when taking photos (see pics). 3 decorative and functional buttons, 2 hidden buttons (bottom), 1 decorative button on front pocket. I can't find the size, but I'm assuming it's a medium. Please see pics for measurements, and ask any questions before purchasing. Ty! 🌻
